To all whom it may concern.-

Be it known that I, JACOB F. BOWMAN, a

citizen of the United States, residing at Artesia, in the county of Eddy and Territory of New Mexico, have invented certain new and useful Improvements in Means for Attaching Rails to Metallic Ties; and I do declare the following to be a full, clear, and. exact description of the invention, such'as will enable others skilled in the art to which it appertains to make and use the same, reference )eing had to the accom anying drawings, and to the letters and gures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in means for securing rails to metallic cross-ties, such means being hereinafter particularly described in the s ecification, and pointed out in the subjoi'ne claims. Preceding a detail description of the invention, reference is made to the accompanying drawings, of which I Figure 1 is a top plan view of a portion of a rail and a portion of a 'metallic cross-tie, showing my improved fastening devices. Fig. 2 is a sectional viewon the ine a: :r of Fig. 3 is a detached plan view of one of the fastening-tongues. Fig. 4 is a detail view of the upper side of a portion of the metallic cross-tie with the fastening-tongue removed. Fig. 5 is a detached view of the fastener.

In a detail description of the invention similar reference characters indicate corresponding arts.

e metallic cross-tie is constructed of pressed steel and comprises an upper side 1 with two downward rlght-an led extensions 2 2. In placing this metal '0 cross-tie so constructed a suitable foundation is provided-such, for example, as concrete or its equivalent. On either side of the rail 8 there are provided in the top of this metallic cross-tie two openings 6 6 and a single opening 7, extending lengthwise of the tie, the openings 6 6 being in line with the flanges 9 of the rail and extend transversely of the tie. C06 crating with these openings, which are dup icated on each side of the rail, are two fastening-tongues or spring-clamps 3, which are provided at one end with an extended ton ue 10, which overlaps the ad acent flange 9 o? the rail 8, and two downwardly-turned tongues 11, which extend into the openings 6 6 in the metallic tie, and thus prevent the tongues or spring-clamps 3 from having any undesirable longitudinal movement away from the rail-flanges 9. The outer ends of said spring-clamps 3 engage in suitable depressions 4 in the upper side of the tie 1, and

thus. provide additional means for main-' taining said spring-clamps against longitudinal movement.

At a suitable point in the body of each of said spring-clamps there is an opening 5, with outwardly-tapering sides and terminating in an oblong form. Coperating with these openings 5, which lie immediately above and in 'alinement with the oblong openings 7 in the tie, are bolts 14, one end of which terminates in an integral head 15, and the other end of which terminates in an integral crosshead 16, which is oblong and is passed through the elongated openings 5 and 7 in the springclamp 3 and the tie 1, and when in such position the said cross-head 16 is made to lie transversely of the spring-clamp and the tie, so that it will lock on either side of the opening 7 in said tie. Thebolt-head 15 lies a ove the spring-clamp 3 and has upon its under side a projection 17, with tapering sides to match the sides of the opening 5 in said spring-clamp, projection 17 lies, so that the cross-head 16 of the bolt engages the under side of the tie 1,

whilejlthe head 15 of said bolt interlocks with the spring-clamp 3 by lying within the opening 5. The resiliency of the bar or clamp 3 is such that it exerts at all times an upward pressure against the bolt-head 15, which serves to prevent the bolt from turning when placed in position to lock said clamp against the rail-flange. In inserting the bolt in such position the spring-clamp 3 is first placed in position with the tongue 10, overlapping the railflange 9, the tongues 11 projectinginto the openings 6 '6 in the tie 1 and the end lying within the depression 4 in the upper side of the cross-tie. The bolt is then inserted by passing the cross-head 16 into the opening 5 of the clamp 3, and said clamp is then pressed downwardly by means of any suitable implement to enable the cross-head 16 to be passed down through the opening 7 in the tie and then turned, so that said cross-head will he or extend across the opening 7 and will interlock with the under surface of the cross-tie,

and in which opening the said whilethehead 15 of the bolt will interlock with the spri -clamp 3 in the manner hereinbefore spec' ed and,' as before stated, the natural resiliency of the spring-clamp will maintain the bolt in such interlocked position.

I claim- 1. A metallic tie having openings in its upper surface lying on each side of the rail, in combination with a spring-clamp which engages the rail-flange and the tie at one end and the tie at the other end, and a doubleheaded bolt adapted to be passed through the spring-clamp and the tie to maintain said clamp in engagement with the rail-flange and the tie. i

-2. A' metallic tie having openings therein lying on each side of the rail, in combination with a spring-clamp, one end of which engages the openings nearest to the rail in the tie and overlaps the rail-flange, a doubleheaded bolt adapted to extend through openings in said clamp and in the tie, one of said heads interlocking with the tie and the other interlocking with the s rin -clamp to prevent rotary movement 0 sai bolt.

-In a fastener for uniting rails to metallic cross-ties, the combination with a metallic cross-tie having suitable openings on both sides of the rail, of a spring-clamp interlocking at one end with'the tie and the rail and at the other end with the tie, a bolt penetrating an opening in the body of said spring-clamp and the tie with means on one end thereof for interlocking with the tie, and means on the other end thereof for interlocking with the spring-clamp to maintain a proper engagement between the spring-clamp and the tie, and the rail, and to prevent said bolt fromturning from a locking position.
